Q2. The diagram shows two of the forces acting on a uniform ladder resting against a vertical wall.

The ladder is at an angle of 60° to the ground.

(a) Explain how the diagram shows that the friction between the ladder and the wall is negligible.

(b) The forces acting on the ladder are in equilibrium.

Draw an arrow on the diagram to show the direction of the resultant force from the ground acting on the ladder. Label your arrow G.
